question

ok, I want that my data base be safe.
so, why if a put this command in the prompt like a regular user

zurron@gpsis:~$ /usr/local/pgsql/bin/psql -d colegio -U postgres

i get this:

Welcome to psql, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help on internal slash commands
       \g or terminate with semicolon to execute query
       \q to quit

colegio=#

and here i can do whatever i want
what must i do for fix it?


colegio=# SELECT version();
                            version
---------------------------------------------------------------
 PostgreSQL 7.2.1 on i686-pc-linux-gnu, compiled by GCC 2.95.3
(1 row)


and

test_ip=# select version();
                                                 version
---------------------------------------------------------------------------------------------------------
